Abstract
Official abstract text for this publication.
The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1, Q2, Q3, R1, R2, R3, R5, and X are defined within the specification.
First claim
Opening claim text (preview).
What is claimed: 1. A method of preparing metal sulfide, metal selenide, metal sulfide/selenide, mixed metal sulfide, mixed metal selenide, or mixed metal sulfide/selenide nanoparticles, the method comprising: (a) contacting at least two precursor metal salts with a sulfur-containing precursor, a selenium-containing precursor, or a combination or mixture of the sulfur- and selenium-containing precursors, or (b) contacting a precursor metal salt with a sulfur-containing precursor…
